Subject: [PATCH] For OpenMPI v 2+, add a configure option to provide C++
bindings. (#1730)
+ Starting with version 2.0, OpenMPI no longer provides C++ bindings by default
(libmpi_cxx.so). Add a configure option to instruct the build to also build
and install libmpi_cxx.so.
+ This MPI feature is needed by at least one spack package (moab).
